IPC: A41C3/00
Filed: 1921-12-07
Abstract: 195,697. Lindemann, E. A. Dec. 7, 1921. BrassiÞres.- A brassiÞre comprises a non- elastic-front panel 9, which is gathered into stay pieces 10, 11 to form a fullness 12, and an elastic back panel. The latter comprises two elastic sections 17, 18 shaped to fit stay pieces 10, 16 cut to the form shown so as to cause a higher tension above and below the breast than over the fullness thereof. The panel 18 is flared outwardly at its lower edge 23 to give reduced tension over the hips. A protecting pad 13 on the front panel carries an eyelet 15 to engage a corset fastener. The length of the upper edge of the panel 9 is slightly less than the length centrally of the panel.

Title: Washing machine with liquid circulation
IPC: D06F15/02
Filed: 1948-12-22
Abstract: 668,845. Washing and drying machines. RAND WASHING MACHINE CORPORATION, H. J. Dec. 22, 1948 [Jan. 31, 1948], No. 33032/48. Class 138 (ii). A washing-machine comprises a flexible liquid and air-tight bag 10 for holding laundry and detergent, means 25 for maintaining a circulation of the detergent within the bag and means 28 for simultaneously withdrawing the detergent and air from the bag to cause the bag to collapse against the laundry to squeeze the detergent from the laundry. The bag 10 is supported within a casing 13 by a cylindrical plate 12 and a bottom plate 11 and has a top opening closed by a self-sealing cover 16 of the type described in Specification 668,844. An opening in the bottom of the bag is closed by a top plate 18 which has a central opening 19 and a plurality of peripheral openings 20 and by a bottom plate 21. The space between the two plates forms a pumping chamber. A perforated post 23 rises from the centre of the plate 18 inside the bag over the opening 19. A vaned impeller 25 is rotatably mounted in the pumping chamber and is driven by a motor 27. Liquid is circulated by this impeller as indicated by the arrows in Fig. 1, entering the pumping chamber at the opening 19 and leaving through the openings 20. An opening 36 is provided in the bottom of the pumping chamber through which liquid is supplied to the bag and through which air and liquid is withdrawn by an aspirator 28 to collapse the bag so that atmospheric pressure may squeezedry the clothing. In use, after soap and clothing are placed in the bag and the cover 16 replaced valve 33 is closed and valve 35 opened, a hot water valve 38 and a cold water valve 32 are then opened as desired to supply water to the bag. When the bag is filled the valves are closed and motor 27 is started to circulate the water and wash the clothing. At the end of the washing period and while the impeller 25 is still rotating valves 35, 33 and 32 are opened which causes the aspirator 28 to suck air and liquid from the bag. The impeller keeps any scum circulating so that it is removed with the liquid and not left on the clothing. The aspirator may be replaced by a pump as described in Specification 640,020.

In a circular machine in which the independent needles are all mounted in the same bed, so as all to draw loops in the same direction when active and in which the stitch length is determined by relative loop drawing movement between such needles and yarn engaging devices alternating therewith, fashioning needles interspersed among non-fashioning needles have their tracks disposed out of the circle of the non-fashioning needles and arranged in such staggered relationship with respect to the tracks of the non-fashioning needles that the linear spacing between each pair of adjacent active needles during their looping drawing movements is substantially the same irrespective of whether or not the fashioning needles are active. The invention is applicable to machines operating as in Specification 723,301. As shown, fashioning needles 2f and non- fashioning needles 2nf are carried in tricks 3f, 3nf of unequal depths.

Abstract: 344,875. Filters. SOC. ITALIANA PIRELLI and PESTALOZZA, U., 21, Via Fabio Filzi, Milan, Italy. Nov. 8, 1929, No. 34216. [Class 46.] Aqueous dispersions of rubber &c. are concentrated by arranging a filtering medium therein, and producing relative movement between the liquid and the filter sufficient to maintain the pores of the filter free for the passage of the aqueous medium until the dispersion has acquired the desired concentration. Suitable apparatus for carrying out the process comprises vessels A A<1> having vertical conduits B B<1>, joined by a horizontal pipe L, with discharge valve F. In each of the conduits B B<1> is a hollow earthenware filter C C<1>, with discharge E E<1>. The clearance between the surfaces of the filters C C<1>, and the sides of the conduits B B<1>, is about 3-4 mm. Latex is passed alternately from one vessel to the other past the filters, by manipulating valves H<1> I, and H I<1>, connected to pressure supply and atmosphere respectively. The rate of filtration can be increased by applying suction to the outlets E E<1> of the filters. Air-bags may be placed in the reservoirs, and alternately distended and collapsed, if it be desired to keep the latex out of contact with the air.
